TELEGRAPHIC CODE.

PECIFICATION forming part of Letters Patent No. 335,929, dated February 9, 1886.

Serial No. 172,108. (No model.)

To all whom t may concern:

Be it known that I, ABRAM G. HoY'r, of Kingston, in the county of Luzerne and State or" Pennsylvania, have invented a new Improvement in Telegraphic Codes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a view of a portion of one page of a standard telegraphic code, having a blank for the arrangement of the private code; Fig. 2, the strip having the same series of code- Words adapted to be cut and applied to the blank column on the page.

This invention relates to an improvement in what is commonly called telegraphic code that is to say, a series of words each of which stands for or indicates several other words which in themselves give specific information, and so that, the single code-word being sent as a telegraphic message, the receiver by reference understands this message to be the several words giving such specific information, and whereby not onlyis the message substantially in cipher as between the parties, but a single word may be employed in place of several words, thereby reducing the cost of the message. Such a series of words is usually in one column on the page of a book, as represented in Fig. l, and in parallel column the phrases or sentences are arranged corresponding to each of the code-words, so that a person desiring to send a message, on referring to the proper subject, finds the message; then adapting the codeword adjacent to such sentence, that word communicated to his correspondent enables the correspondent on its receipt to refer to the code-words, and finding the code-word which he has received .understands it to convey to him the message indicated adjacent to that word. These codes are usually printed in book form, occupying many pages; but in telegraphie correspond ence the same code-word will be known to indicate the particular sentence adjacent to that word in parallel columns Ain the book, so that while for general use such a code is useful it is not adapted to private telegraphie correspondence between certain parties..

The object of my invention is to retain the standard code, and yet adapt the same codewords to different expressions or sentences; 5 5 and it consists in combining with a printed telegraphic code consisting of a series of code-words printed in one column and a cor-- responding series of expressions printed in a parallel column, cach expression' adjacent to 63 its code-Word, the same series of code-words printed upon a strip independent of the page or printed columns of words and expressions, the said strip adapted to be applied in a column parallel with the said column of expressions, and so that by a division of the column a different arrangement of the same code-words may be made for the expressions on that page, as more fully hereinafter described. 7o

In Fig. l I represent a portion of a telegraphic code. In the first column is the usual code-number, not essential, however, to 'this invention. In another column are the codewords which are to be used in the communi- 7 5 cation. In another column the expressions are arranged, one to cach code-word, and in the usual manner of arranging t-elegraphic codes. A third column or blank space, A, is provided parallel with the column of eode- 8o words. On a strip, B, independent of the page on which are the standard code-Words and expressions, I print the same series ot' code-words as in the standard code, and pref erably so that in the column they stand in the 8 5 same relation as in the standard column, and as seen in Fig. 2. This strip B is adapted to be applied to the page parallel with the codewords. The strip may be prepared with a suitable adhesive material, so as to be simply 9o moistened and applied to the page; or the adhesive material may be applied at the time ofplacing the strip on the page.

To illustrate the use of my invention, suppose certain parties having` the standard code and the strip desire a private code for the same expressions, which shall only be known to themselves. The strip B, having the series of code-words printed thereon the same as the standard code, is first eut, say as upon the rco line a-that is to say, cutting off five Words from the top of the column. rlhen the remainder of the strip is applied to the blank column A, each of the code-Words in line with the adjacent expressions, so that in the illustration,instead ofthe column commencing with Gistercian,77 the column will commence with CitrowJ Then the five Words which are cut off will be applied at the bottom of the'column to complete the page. Thus While retaining upon the same page the same code-Words, they are so differently arranged that each of the newly-arranged code-Words conveys a different expression from that of the standard code. This illustration will be sufficient to enable those skilled in the use of telegraphic codes to adapt the strip to a great variety of codes for the same expressions, yet retaining the same code-Words, and so that the private code-words may be found upon the same page as the standard code-Words, and Where it is desirable several independent codes may thus be embodied in a single book, one being the standardcod'e, the others private, andall so differ,

ent from each other that it will be impossible for persons unfamiliar With the private, codes to decipher them.

I claim- In a printed telegraphic code consisting of a series of code-Words printed in one column and a corresponding series of expressions printed in a parallel column, each expression adjacent to its code-Word, the combination therewith of the same series of code-Words printed upon a strip independent of the page or printed column of Words and expressions, the said strip adapted to be applied in a column parallel with the said column of expressions, substantially as and for the purpose described.
